Article_FuzzyPIDcontrol
The advantage of static controllers is in their simple structure, however, their performance is not good. Therefore, in fact, the fundamental fuzzy controller is often combined with conventional ones (e.g., PID controller) to create a dynamic fuzzy controller to have higher control quality. there is an PIDFuzzycontroler example

apf-15.8.15
针对智能车路径规划的问题,采用人工势场法进行智能车的路径规划,进而为智能车提供一条安全无碰的较优路径。本程序基于源程序进行了改动,松弛了迭代终止条件,避免智能车绕过目标无限探测下去。(Smart car for path planning problem, the use of artificial potential field of intelligent vehicle route planning, thereby providing a safe path for the optimum touch smart car. The program is based on the source code made changes, relaxation iteration termination conditions, avoid detection infinitely intelligent car rounded the target down.)

说明: 交通视频采集后的图像预处理。由于硬件及环境等因素的影响,摄像头提取的图像不可避免地包含噪声,图像的质量会受到不同程度的失真。因此,我们要对采集到的视频序列进行图像的预处理。
车辆检测算法。概括性的分析了基于图像处理的几种常用的车辆检测算法:帧差法、光流法,总结了各种方法的优缺点,并采用背景差法对车流量进行检测。该算法自适应能力强,计算量小,可正确判断有无车辆、完成车辆计数,实现车流量计算,为交通监管系统提供实时有效的交通参数。
车辆计数。分析常用的车辆计数方法:虚拟线圈法和目标跟踪法。并结合具体的实际应用采用基于检测带的车辆计数方式。结果表明,该方法能很好的进行车流量统计。
(Image pre-processing traffic after video capture. Due to hardware and environmental factors, the camera inevitably contain the extracted image noise, image quality will be subject to different degrees of distortion. Therefore, we want to capture the video sequence image preprocessing.
Vehicle detection algorithm. General analysis of several common vehicle detection algorithm based on image processing: frame difference, optical flow, summed up the advantages and disadvantages of each method, and using background subtraction to detect traffic flow. The algorithm is adaptive ability, a small amount of calculation can correctly determine whether the vehicle, the vehicle should count to achieve traffic flow calculation provides effective real-time traffic parameters for a traffic monitoring system.
